N2 - The relations between the anisotropic magnetoresistivity ratio Δρ/ρ0, the ordinary Hall coefficient R0, and the extraordinary Hall coefficient Rs were studied for Ni-Fe binary alloy and for (Ni89.5Fe10.5) M (M = Co, Cu, Nb, Gd, Al, Si, and Bi) ternary alloy thin films, to obtain guidelines in searching for new materials with large values of Δρ/ρ0. It is found that the value of Δρ/ρ0 increases with increases in the absolute value of R0, and also shows a maximum (Δρ/ρ0 ≈ 4%) at RS = 0. For ferromagnetic metals, a large value of Δρ/ρ0 can be obtained under the following conditions: (1) the sign of R0 is negative and the absolute value of R0 is large (carriers are electron-like and the effective carrier density ηeff is small), and (2) Rs is zero. Sample preparation and experimental procedure are described, and the results are discussed.
